We have a 3 site environment with several T1s between sites. We are replacing those T1s with a metro ethernet type switched WAN link. Our routers will be replaced with Layer 3 switches at each remote site.
My question is if it makes sense to create a VLAN on our core central switch for each site and create VTP trunks from the core switch to the remote switches? Does this make the most sense? We also have VOIP traffic as a consideration so will need to segmeent that traffic as well.
